Bought as a gift so not used myself, trusted the brand and need my friend safe, bought spray as well , new biker and her glasses steaming up.. if foggy can wear it then am buying it lol..
At first i thought the price was a little steep but after using it i will never ride in winter without one again. I tried all the tricks, pinlock inserts, shaving foam, hydrophobic coatings but nothing works as well as simply stopping your breath from hitting your visor. Great product, fair price, essential gear for winter riding. Can not recommend this enough.
